GENERAL

▶ [patch] [6498](https://github.com/taskcluster/taskcluster/issues/6498)
Github service auto cancels previous builds by default now.
This behavior can be disabled by setting `autoCancelPreviousChecks` to `false` in the `.taskcluster.yml` file.

OTHER

▶ Additional change not described here: [6571](https://github.com/taskcluster/taskcluster/issues/6571).

GENERAL

▶ [patch] [6564](https://github.com/taskcluster/taskcluster/issues/6564)
Fixes CSP related issue with running single UI container locally `docker compose ui`. If run with shipped nginx.conf, it would not be able to load some resources correctly because of the stricter 'Content-Security-Policy' headers.

GENERAL

▶ [patch] [2940](https://github.com/taskcluster/taskcluster/issues/2940)
Prepares azure_queue_messages table for upcoming migration by adding `task_queue_id`, `priority` columns.

▶ [patch]
D2G now takes advantage of Generic Worker Indexed Artifacts, introduced in Generic Worker 51.0.0. D2G translates Indexed Docker Images into Generic Worker mounted Indexed Artifacts. Previously, D2G generated commands to query the taskcluster Index and fetch the docker image.
With this improvement, docker images are now cached on workers, docker image dependencies between tasks are declarative (and thus inspectable), and generated Generic Worker task payloads are simpler and easier to understand.

USERS

▶ [minor] [6553](https://github.com/taskcluster/taskcluster/issues/6553)
Generic Worker File Mounts now include an optional `format` field to specify the compression format for the content. Generic Worker will decompress the retrieved content using the format specified before writing to disk. To avoid decompression, do not include the format field.

Allowed compression formats are: `bz2`, `gz`, `lz4`, `xz`, and `zst`.

This change additionally adds support for the `tar.lz4` format for Writable Directory Caches and Read Only Directories.

GENERAL

▶ [patch]
Updates ubuntu image versions to `jammy`.

GENERAL

▶ [patch] [6543](https://github.com/taskcluster/taskcluster/issues/6543)
Generic Worker: d2g no longer passes the environment variable values to the `podman run` command. Instead, just the variable name is passed as `-e VAR` which tells podman to take the value from the host. This will tidy up the run command and will help with any escaping issues users may have been having.

DEPLOYERS

▶ [minor] [5514](https://github.com/taskcluster/taskcluster/issues/5514)
Adds support for postgres version 15.

Note: if you want to migrate your local dev db to pg15, you'll need to either erase the existing db with `docker volume rm taskcluster_db-data` before you migrate, or, if you'd prefer to keep your local dev data, you'll need to manually dump the db contents and then import them into the upgraded db.

Support for postgres v11 will be dropped from Taskcluster on November 9, 2023 (v11 EoL date) and that will be a breaking change.

▶ [patch] [6534](https://github.com/taskcluster/taskcluster/issues/6534)
Upgrades kubernetes cronjob api version to `batch/v1`.

WORKER-DEPLOYERS

▶ [patch] [6540](https://github.com/taskcluster/taskcluster/issues/6540)
Generic Worker panicked when evicting caches to free up space on workers. This was reported via sentry [here](https://mozilla.sentry.io/issues/4044685700/?project=6462337).

USERS

▶ [patch] [6470](https://github.com/taskcluster/taskcluster/issues/6470)
D2G now properly escapes artifact paths in generated `podman cp` commands.

▶ [patch] [6488](https://github.com/taskcluster/taskcluster/issues/6488)
Generic Worker no longer panics if an IO error occurs while scanning the filesystem for artifacts.

▶ [patch] [6516](https://github.com/taskcluster/taskcluster/issues/6516)
Generic Worker now handles Indexed Docker Images where the docker image
contains multiple tags. Previously, Generic Worker assumed that indexed docker
images would have only one tag.

DEVELOPERS

▶ [patch]
Updates Github integration documentation to tell which events to subscribe to.
